*Active Fluidics settings reflect target intraoperative pressure (IOP) and are presented as IOP setting, mmHg (equivalent bottle height, cm H₂O).
^†Occlusion break surge was assessed using 6 fluidics packs per system, including tubing and cassettes, tested in triplicate. Vacuum rise was assessed using a minimum of 3 fluidics packs per system.
^‡IOP target of 65 mmHg only.
